There has been a shortage of helium, a crucial component in the manufacture of fibre optic glass, in part caused by plant outages in Russia and the US, which has caused prices of the element to increase by 135 per cent over the past two years. Meanwhile, prices of silicon tetrachloride, another key component in fibre production, have increased by up to 50 per cent according to Cru.
“In my professional career I’ve never seen anything like this inflationary crunch,” said Wendell Weeks, chief executive of Corning, the biggest producer of fibre optic cable in the world, which played a significant role in inventing the technology in 1970.
Weeks added that the company was ramping up production to meet soaring demand from governments, telecoms companies and big tech groups, including building new facilities in the US and Europe.
